请教GWD2-29？

29. Several
financial officers of the company spoke on condition that they not be named
in the press reports.

1. that
        they not be named
2. that
        their names will not be used
3. that
        their names are not used
4. of not
        having their names
5. of not
        naming
        them                     
        

这一题答案给的是C, 但我觉得应该是A。

今天看白勇的语法全解，第91页有一道相当类似的题

18. Several senior officials spoke to the press on
condition that they not be named in the story.

A. that they not be named

B. that their names will not be used

C. that their names are not used

D. of not being named

E. they will not be named

这题答案是A，因为C的条件从句的一般现在时（are not
named）与主句的一般过去时（Spoke）不协调。

两题貌似很相似，那么, GWD2-29是否应该选A？
